I have an idea for a turbo...

[nrsjs]

it would not matter how fast the second motor was because it is not using electricity to drive it it is using the other motor. the only thing that would limit it would be friction.

do you understand what he's trying to do at all? He's using the first motor as a GENERATOR (GENERATES ELECTRICITY) and he wants to use that electricity to run the second motor. And it would hardly create any electricity, so the second motor would be providing about 20% (at the very most) of the power that the first motor is making, which means that the first motor is gonna have to fight against the second motor to run at any decent speed

no no no the second motor is generating additional energy for the fist like a boost

so technically you would gain 20% power form the turbo

personally ied just pop another batter in there saving weight an there would be no where else for the motor to lose power by pushin another motor

[Bleek]

the loss wopuldn't be noticed only the gain would be noticed and not only is the gain it applied when and where u want it most at high rpms and after the pcb so the additional power isn't restricted by passing throught the pcb to get to the motor. think bout it... it just makes sense

[pbmax]

Well, no, it doesn't make sense at all. No offense

You're talking about gaining more from the generator than you lose to generate the electricity. It's a lovely idea, but just like the perpetual motion machine, it's quite impossible. If it were possible, we'd have electric motors all over the place with no power sources generating all the electricity in the world! Who needs oil!?!?

If you really want a "turbo" mod, why not just hook 2 motors to the drive train? You wouldn't need any additional voltage if you wire the motors in parallel (voltage drops across parallel circuits are the same). Of course your current draw would be much increased, which might be an issue for the stock speed controller on the PCB, and possibly an issue with max current draw from the batteries (approximately double normal current draw). In any case, your battery life would be half what it normally is, even if it could handle the extra draw.

As a side note, when will people learn that a turbo is an exhaust-gas driven supercharger; a forced induction device that pushes more AIR into an engine. The key word here is AIR, not electricity.

Where do you get this 20% figure?
How would you keep the motor from using electricity?

I think you need to read this thread, this has been discussed already, and it will not work.

A wonderful idea, an alternator

some of you aren't understanding the concept. the second motor is running off the power driving the car so there is no loss in energy only a gain. it might not be as much as desired but u will notice it as the rpms increase and more evergy is generated. but i want to talk to some of u on ain for a thorough explaination

to make it work you'll need to put some diodes between the "generator" and the motor driving the motor so that the second motor isnt driving too.

and its only supposed to give the effect of a turbo. Effect is the key word here

[tavisjohn]

It still would NOT work. The drive motor would have more drag on it than the "Generator" would generate energy. Look at the other forum I listed above. ALL this was ALREADY discussed, and all the scuienrific explinations were already listed there.

The next one of these argument topics:

"hi u guys where can I get some plutonium so i can put a radioisotope thermal generator in my xmod? i don't feel like spending the money on i-c3's. thx"

[Bleek]

yeah the effect is the only simularity besides the gain. having it run off back presure on x-mods through exhaust is nearly impossible, stating that nothing is impossible. but i think it is possible with very little resistance and a low torque second motor generator.i am working on a working model right now and i am almost done. if and when it's completed i will try to put a movie on to show everyone.

[nrsjs]

xmods don't have exhaust sparky, they have electric motors

and how exactly do you plan on making this miniature 'low torque second motor generator'?

[Bleek]

very carefully........

ok what yall are talking about confused me for a min but then i cought on to what you wanted to do but for me to explain what would be need ed to do this it would be easier to make a video and sho all of you see the problem comes in when you connect the other motor to the main motor well one the turbo would have to generate more voltage at the same rpm than the one driving the car, Two if you connect the two positives and the two negatives you going to have both motors driving and you will get the same power out put that if you had one motor THREE If you wanna do it right the firs t ime your gonna need some thing called a diode and all the specs for this to stop the voltace from going to the other turbo motor and driving it a diode actually is a one way valve it allows electricity to go one way but not the other so you need 2 diodes to stop the electricity to the second motor that is the only way i can think of doing this it is a good idea and i am gonna try it i will produce more specific details on it and all the part numbers on what you will need to do it and i will tell you if it is worth it and if you don't think i know what i am talking about i had 2 years of electronics and i graduated top of my class i will produce more specific details

well im no pro and my electronic expertise in no way even comes close to NissanGTR01 but i am a good thinker, a turbo is a fantastic idea, but with two motors its tricky, a simpler and lighter way would be to install two extra batteries in series (6th cell mod) then using diodes and timed resistors and a bunch of other components (electronic nub)... and possibly some how get the car to run on 4 cells and then after say 5 seconds of full throttle the voltage would increase gradually,(so at first youd have a resisted 4.8V and after 5 seconds of blasting it, the resistors would gradually let off giving you 7.2V) raising voltage,and thus raising speed. you could then swap the timing resisitors to any time or buildup rate you wish, from like 0 seconds which is usesful for tire spinning drifiting, to a say 5 seconds for the best traction... this is just my imput, and i was hoping some of you experts could tell me what you think

im also aware that this can be acomplished by gradually increasing the throttle but this way sounds funner, and also the low to high ( simulated nitrous) button sounds promising..

[Daazndood]

how about having 6 cell and 2 motors? or is that too much.
